But why did it take this long? For many people, myself included, facebook is a kind of social calendar.  And even though you could share an event you are attending with facebook, there was no way to see what events your friends are going to unless there was also a corresponding facebook event. Now, Eventbright has an ‘event graph’ that provides this function.  How deep will the integration will go remains to be seen, however, I expect there will be a flood of other ‘event’ services following Eventbrights lead.

As good as this is for Eventbright, this is a big win for Facebook because as more and more services following Eventbrights lead, facebook will become the defacto social calendar regardless of the services you use.

The only question I have is; why did it take this long?
